{SPECIFICATION forming part of Letters Patent I l'o. 31%,378, dated March 24, 1885.

(No model.)

To (ZZZ whom, it may concern.-

Be it known that I, WVILLIAM IL HARRIS, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Utilizing \Vaste Hoop-Iron, 850., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a top view of the machine; Fig. 2, a front view, and Figs. 3 and 4 views of the product.

My invention consists in utilizing waste or refuse hoop-iron (such as cotton-bale ties that have been used and are worthless unless melted and put into a new form) by passing it between rolls to reduce it in thickness and width, and then cutting it into lengths about.

necting the cross-strips by which a number of shingles are held together-as shown in the diagram at the bottom of the drawings. This scrap hoop-iron can be purchased very cheap, and with a small expense can be passed through rolls to reduce it to the properthiele ness and width to perforate and cut it off, and in this condition it brings a good price and has ready sale.

Referring to the drawings, I will describe one form of machine for carrying out my invention.

A represents an under plain roll, and B an upper flanged roll, supported in a suitable frame, G, and connected by gear-wheels D. On the shaft of one of the rollers is a drivingpulley, H. The metal is first heated and then fed to these rollers between guides I, and is forated by pins or projections J on the upper roller, which enter recesses N in the under roller, and then the strip is cut off by a trans verse knife, 0, on one of the rollers. and immediately behind this knife are pins P,i'or perforating the first end ofthe next strip, so that both ends are perforated, as shown in Fig. 4. This finished strip is lettered U, and V represents a piece of the hoop-iron before treatment, except the upper end, Fig. 3, which is shown as having been treated. The sides V, which are cutoff to make the strip the proper width, are worth as much for scrap to be melted up as the hoop-iron itself. These strips for binding shingles havebeen heretofore made from good and valuable wroughtiron. strips, which have to be perforated and cut in a manner very similar to that above described, so that the cost of producing them is about or just the same, while the first cost of the material is several times as much as the scrap hoop-ircn used in my improved method.

I claim as my iuventiou The method herein described of utilizing waste or scrap hoop-iron, &c., which consists in passing it in a hot condition through rolls to reduce it to the proper thickness and width, then perforating it and cutting it into proper lengths for binding shingles, as set forth.
